Quote:If man evolved from monkeys and apes, why do we still have monkeys and apes?
The pattern of evolutionary processes that we see (in the fossil record and living species) can be of two types:
In anagenetic (meaning "that generate upward movement") events, an entire population evolves in one direction and becomes so different that at some point the people who study it give it a different name. This is encountered in paleontological research and the decision to separate one from the other is ultimately arbitrary.
Cladogenetic (meaning "that generates branches") events entail a population that splits into different sub-groups; each of these then evolves independently from the others.
Many people still think that there are fossils that are "missing links". That term is very outdated and belonged to a view of evolution as a gradualist "progress" toward mammals and ultimately, men. But the tree of life is exactly that, a TREE, and there is not a single predominant stem.
All the species that are living today have their separate evolution and history; also they all share common ancestors from which they have inherited our common traits. And apes have their own ancestors that are closer to them than to Homo sapiens; the fact that apes are our closest living relatives does not exclude the existence of more related _extinct_ relatives.
We share A COMMON ANCESTOR with living apes, but we have not evolved from them directly.
Our direct ancestors are fossil hominid species.
Evolutionary processes are long-term phenomena, and it may seem that there are "evolutionary leaps" from one species to the other. But most of the "leaps" are due to the fragmentary nature of the fossil record. So many populations become extinct or become something else and their former existence is not recorded anywhere! But although the record is fragmentary, life is continuous. All species are evolving today (including us, although the patterns that arise from our current evolutionary processes will become apparent a long time from now), and modern ape species are not the same as they were millions of years ago.
(In short we didn't)
